The developer portal provides API definitions that include working code examples and the ability to make authenticated API requests directly within the documentation. This section provides step-by-step instructions on how to make API calls from the developer portal.

#### Prerequisites

- Install the [Postman](https://www.postman.com/downloads/) client.
- Generate the access token by following the instructions in the [Getting Started with fabric APIs](https://developer.fabric.inc/v3/getting-started/api-guides/getting-started-with-fabric-apis) section.
- Get the `x-fabric-tenant-id` by following the instructions in the [Getting the Account ID](https://developer.fabric.inc/v3/platform/settings/account-details/getting-the-account-id) section.

### Procedure

1. Go to the [fabric Developer Portal](https://developer.fabric.inc/).
2. To try an API endpoint, go to the corresponding page.
    
For example, to add an attribute go to the [Create Attribute](https://developer.fabric.inc/v3/api-reference/product-catalog/attributes/create-attribute) page. You can click the **Examples** menu in the request field to view request examples with data.
3. To run the API request, do the following:
   - In the **Bearer** field in the right pane, enter the access token.
   - In the **BODY PARAMS** section, enter the required setting for each parameter.
   - In the **Headers** section, enter the required setting for each parameter.
   - In the right pane, click **Try it**.

The response is displayed in JSON format. You can also click the Examples menu in the right pane to see different response examples.
